PhI(OAc)2/KI mediated 1,2-acetoxysulfenylation of alkenes: facile synthesis of β-acetoxysulfides
摘要:
A convenient method for 1,2-acetoxysulfenylation of alkenes using disulfide promoted by (diacetoxyiodo)benzene (PhI(OAc)(2), DIB)/KI was developed. The reaction is highly regioselective for styrene derivatives while aliphatic alkenes lead to a mixture of two regioisomers. (c) 2013 Elsevier Ltd. All rights reserved.
study of the oxidation of 4-methoxyphenethyl phenyl sulfide and 3,4-dimethoxy-phenethyl phenyl sulfide with potassium 12-tungstocobalt(III)ate [Co(III)W] suggests that in the radical cations of 3,4,5-(MeO)3PhCH2SPh (4) and 2,4,6(MeO)3PhCH2SPh (5) the positive charge is not localized on the sulfur atom, but in the benzylic aromatic ring. Nevertheless, in the biomimetic and microsomal oxidation of 4 and

the synthesis of thio-substituted esters throughcopper(I)-catalyzed intermolecular 1,2-estersulfenylation of styrenes with peroxyesters and disulfides was developed. In this transformation, two new C–S bond and C–O bond were constructed simultaneously under a copper catalyst system, and the transformation exhibits a broad substrate scope and good functional group compatibility. In addition, this method
